' strong andrigid so as to be capable of withstanding shocks andpressures, for example, the inertia thrusts of shifting cargoes, and soas to' act as a reinforcement for the car superstructure as a whole, andwhich may be manufactured and installed more economically andconveniently'than the sheet metal ends heretofore employed in theconstruction or repair of railway cars.

Having in view particularly the hard usage to which the ends of freightbox cars are subject due to shifting cargoes and like causes,'cars ofthis sort have been equipped,

either in their'original construction or in the repair of broken ends,with end structures consisting of one or more sheet metal elementsformed with horizontal ribs or" pressed corrugations which carry thestresses exerted thereon as beams to the corner posts l of the car.

. The primary object of this invention is to provide a carend-structure, suitable for use,

either in the constructionof new cars or for repalr purposes, consistingof a plurality of metal end sheets extending from substantially the roofof the car to the floor, suitably joined together and to the cornerposts of the car along their vertical edges and provlded with verticallyarranged parallel corrugations extending substantially from the top tothe bottom of the structure so as,

in eifect, to form upright load carrying members which help to supportthe roof and M a which serve to rigidify and strengthen the end wall ofthe car and thereby the entire frame members of the car.

The invention has for further objects such Specification of LettersPatent.

The end structure in the preferred form shown is composed of acorrugated panel consisting of two sheet metal elements 16, an upperrigidifying and attaching member or metal end plate element 17 (Fig 4:)"and a lower angular rigidifying and strengthening member 18 (Fig. 5).The end sheets 16,

16 are formed with vertical corrugations 19 which extend acrossthe'sheets from top to bottom, that is, from the upper to the loweredges thereof. The sheets are formed on their outerlateral edges withangular flanges 20 which are secured to'thecorner posts 12 by anysuitable means, for efXample, the bolts 1 i 21. The meeting edges of thesheets 16fare preferably provided with angularly disposed flanges 22fastened together by rivets 23.

The top member or metal end plate 17 is se- 1 cured to the wooden endplate 10 by'bolts 2 1, or other suitable attaching devices and hasflanges 17 (Fig. 4) overlapping and'secured to the side wall of the car.Thelower edge of the top member overlaps the upper g,

edge of the panel 16, 16 and has a corrugated or undulatoryconfiguration correspending with the corrugated configuration o'f thepanel. The panel and top memher are secured together preferably by iey,
